SPRING FOR VEHICLES.

SPECIFICATION forming' part of Letters Patent o. 248,023, dated October 11, 1881.

Application iled July20,1881. (No model.)

To all whom it may concern v Be it known that I, SAMUEL GHITTENDEN, a citizen ot' the vUnited States, residing at VVillimantic, in the county of Windhamnnd State ot' Connecticut, have invented certain new and useful Improvements in Springs for Vehicles; and I do hereby declare the followv -ng to bea full, clear, and exact description of the in venlion, such as will enable others skilled in `the nrt to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters or figures of reference marked thereon', which form a part construction in themselves as those described in my before-mentioned allowed application.

It has been foundin practice that the downward pressure of the body of thc vehicle causes the inner ends or curves, a b, otl the tortuous spring B to bend down, and thereby lose their elasticity' and also incur the danger ol' being broken. This is especially the case when the vehicle is heavily loaded and the weight on one end ot the spring is in excess of the weight on the other end. Itis also. found that when the vehicle is heavily loaded and subjected to. a sudden jostling the eurvatures a b will turn downward and the greatest strain will be exerted thereon, rendering them very liable to fracture. To obviatc these diflculties and prevent the downturning of lthe 'curved ends a b, I secure said ends together b v means of alink, C, which, as shown in the drawing, is passed around the ends and across the space intervening between them, so as tohold them together wiinnnn :inenting their individn'ni yielding movement, excepting that by this arrnn gement the ends are prevented from turning downuted over both portions ot' the spring than is the ease where the ends a b are not connected together.

I) represents one of the hanging bars. In the under face ofsaid bar D is a deep concavity, into which the entire top portion of the outer or elliptic spring, A, tits, and l extend the ends of said bar beyond the outer ends of the elliptic spring and bolt orotherwise secure the springs and hanging bar and axle together, as shown at e e.

By constructing the bar D to receive the top portion of the spring A and similarly curving the upper face of the axle E, Isecure improved benring-surl'aees for the spring, and am also enabled to dispense with the leaf or additional rc-eni'orcement of metal usually employed in conjunction with elliptic springs.

Having thus described my invention, what I claim as new therein is- 1. The combination of` the hanging bar I), recessed on its under face, the axle E,recessed on its upper face, the outer elliptic spring, A, the inner tortnous spring, B, link C, and fastenings ccfor securin g said bar, axle, and sprin gs together, substantially as and for'the purpose set forth.

2. The combination of the outer elliptic spiing, A, the inner tortuous spring, B, and the lilik C, substantially as and for the purpose set f'orth.

In testimony whereof I atlix my signature in presence of two witnesses.

SAMUEL C HITTENDEN.
